Blue hair = no education?

So… A kid wants to dye his hair blue, probably in part because his older brother has dyed hair too. His mother figures the right thing to do is tell him “If you get good grades, you can have blue hair”. So then the 6th grade kid works hard, gets good grades, and his mother lets him dye his hair.

The schools response? He's expelled until his hair is back to a “normal” colour.

Hey, they don't call America the melting pot for nothing. If you're not the same as everyone else, you have no right to an education, employment, housing, etc.. Hmmm… Sound like any other countries that got bombed recently?
